NGC6384 is a spiral SAB(r)bc type galaxy (Weinzirl et al. 2009) at a distance of 23.9 Mpc or 77.9 Mly from us (Tempel et al. 2016). Its stellar mass and boxy bulge structure (Erwin & Debattista 2013) makes it appear very similar to the Milky Way.

The majority of spiral and elliptical galaxies in the Universe host very dense and compact stellar systems at their centres known as nuclear star clusters. NGC 6384 is not an exception and embedded within the NGC6384 large-scale boxy bulge exist a nuclear star cluster. The nuclear star cluster of NGC6384 shows a fairly red colour typical for a galactic nuclear source, which can be composed by a mixture of old and young stellar populations. Negligible fraction of the light was found to come from a weak active galaxy nuclei (AGN) that means if a massive black hole (MBH) of NGC 6384 is present, then it might not be accreting, similarly to those in the Milky Way and Andromeda galaxy - M31 (Georgiev et al. 2019).
